Abstract: A network is coupled to the gate electrode of a FET for generating a negative gate electrode voltage having a selected nominal value for minimizing intermodulation distortion of the FET and/or a value varying with respect to the nominal value directly proportional to temperature changes to provide a constant gain for the FET.

Abstract: There is disclosed a monopulse radar system that eliminates scan modulated amming and which scans returning radar signals at filters rather than antennas and converts the signals to frequency modulated information rather than amplitude modulated information. The frequency modulated information is then detected.

Abstract: An electronic thickness gauge for measuring the coating thickness over magnetic and over conductive, non-magnetic substrates by measuring the movement of the low-frequency hump in the response curve for an over-coupled, double-tuned, open-faced transformer when the above-mentioned substrates are placed across the gap between the transformer pole-faces.

Abstract: A dual-motion firing device having both its firing and its arming mechani internal to its tubular housing. A tubular sear is enclosed by the housing and, in turn, encloses an arming rod, both sear and rod extending out of the housing. A tubular firing pin capped and nippled on its forward end encloses the front end of the sear. Pushing the arming rod forward releases a ball which restrains the sear from rearward movement. Then, pulling the sear backward releases another ball which prevents forward motion of the firing pin and a spring propels the latter forward sharply.

Abstract: An economical system for both recording multiplexed digital data on a tape recorder and decoding the stored data.

Abstract: In a two-phase, charge-coupled device having alternate rows of internal and verlapping external electrodes, the external electrodes are fabricated from polysilicon instead of aluminum as heretofore, the internal electrodes also being of polysilicon. Sets of corresponding electrodes are then connected to a bus bar at each end, each bus bar for the same set of corresponding electrodes carrying the same phase, or clocking, signal.

Abstract: A ceramic prosthesis of high aluminum oxide suitable for the tibial plateau of a knee joint with the superior (upper) portion of the prosthesis being of a high density AL.sub.2 O.sub.3 having a very low porosity and the inferior (lower) portion being of high density AL.sub.2 O.sub.3 having a high degree of porosity capable of accepting bone growth.

Abstract: A TWT energizing circuit for compensating for the voltage droop at a TWT hode comprising the use of a differential amplifier which takes a modulation pulse at one of its inputs and a feedback signal comprising a sample of the body current from the TWT helix at the other of its inputs and applies a signal representative of the difference therebetween to the TWT grid. The above-described feedback circuit forces the grid voltage to track the cathode voltage thus maintaining a constant grid-cathode voltage drop.

Abstract: A method with wide process margins for producing a plated-wire memory elet with both good unipolar disturb resistance and burst read resistance. The method comprises adding the additional process step of dipping the wire after the first permalloy layer or a portion thereof has been plated into a bath of a chromium chloride solution so that a thin, discontinuous chromium chloride film overlays this inner permalloy layer. The rest of the first permalloy layer (mated-film process) or the second permalloy layer (mated-film process) may then be plated over this chromium chloride film.

Abstract: A differential depth indicator for measuring the attitude of an underwater able which is being laid. Pressure transmitting points are spaced in an array which attached to the cable being laid, and the pressure at each point is transmitted via fluid conduits to differential pressure transducers. The transducers give an electrical indication of the differential pressure which is sent to the surface where it may be visually displayed.

Abstract: Means for directing and enhancing the explosive energy of a torpedo in a preferred direction comprising a shaped charge with a concave liner, which may be spheroidal, a peripheral ring of spaced detonators at the rear of the charge, a ring of spaced sensors at the front end of the torpedo and connections from each sensor to the detonator which it activates, the detonator being located on its ring diametrically opposite its associated sensor on its ring. Activation of the sensor causes its partner detonator to initiate detonation of the main charge, the resulting shaped charge jet forming a cavity in the water oriented toward the target which activated the sensor. Before this water cavity has time to collapse, its presence causes a disproportionately high amount of explosive energy to move in the direction of the cavity, viz toward the target, enhancing the damage-producing effect of the explosive charge.

Abstract: A detonator for detonating the unfired motor charge when the warhead charge f a rocket missile explodes. The detonator comprises an insert comprising a pair of frusto-cones in parallel relationship, the sides being sealed to each other at the base end and open at the apical end so that the space between the sides can be filled with explosive before the opening is closed. The insert is placed on top of the motor head plate and below the warhead base plate with its concave side facing the motor head plate.

Abstract: An epicyclic transmission of the class wherein rotation of a crankshaft is ransferred to an output shaft by means of discs mounted eccentrically on the crankshaft, operating stably over a wide range of operation. All of the centrifugal forces developed in the various rotating members are compensated to improve stability. One embodiment includes shoulders integral with the discs abuttingly engaging guidetracks integral with the transmission housing for transmitting centrifugal forces to the housing. Another embodiment includes pin support means for counterbalancing skewing forces which result from unsynchronized disc rotation. A third embodiment utilizes a cage comprising supportings and bars for transmitting torque to the output shaft. A fourth embodiment utilizes a planetary gearing arrangement for transferring input rotation to a plurality of driver shafts. The rotation of the driver shafts is transferred to the output shaft by a plurality of seating rings.

Abstract: An electrical explosive igniter, or initiator, of the cylindrical type hag electrical leads coming through to a bridge wire in an ignition mix container. An anvil cutter of cylindrical shape is force-fitted into the center of the igniter and a movable piston is spaced therefrom. The piston has a tapered internal boring. When the piston is forced sharply backward by the internal pressures of the ignited explosives, it shears the wires against the anvil cutter and the tapered portion forms a tight metal-to-metal seal between the anvil cutter and the igniter wall. The greater the pressure, the better the seal becomes.

Abstract: A cylindrical discharge manifold for an electrostatic gas-dynamic discharge ystem in a helicopter comprising four symmetrically positioned air outlets set in the end of a tubular manifold casing which protrudes out from the helicopter fuselage. The outlets connect to a central high-velocity air-stream inlet pipe in the casing by way of a plurality of air passages extending radially outward from the central inlet pipe. This manifold design insures a symmetrical air distribution, significantly reduces drag pressure on the aircraft, and obviates the requirement for "Y" air hose connections.

Abstract: A "Gerdien Condenser" spectrometer for use in a moving air environment for measuring ion densities wherein a constant, electric field is provided in the direction opposite to prior art devices so that the outer cylindrical electrode of the condenser functions as the ion collector. This functional change for the outer electrode permits the use of a small-radius annular opening with a larger width as the entrance for the ions to be measured. This change in the shape of the entrance to the condenser chamber substantially reduces the gas turbulence within the chamber thus increasing the ion density measurement accuracy. The outer electrode may be segmented to further increase the ion measurment accuracy.
